Application led Dotober 20,1917. Serial No. 197,710.

To all whom it may concern Be it known that I, EZRA DIXON, a citizen Y of the United States, residing at Bristol, in the county of Bristol and State of Rhode Island, have invented a new and useful Improvement in Top-Roll Saddles, of whichv the following is a specification.

The invention relates to certain new an useful improvements in a front top roll saddle especially used in the art of spinning for riding on the front roll of spinning machines to permit pressure being applied therethrough to the roll, and it has for its principal object to embody a simple lubricator in the saddle construction for furnishing the bearing surface the required and continual lubrication.

Specifically, the invention comprises a saddle for front rolls having a bearing in its `under side which is formed with a depression; a well formed in the upper side of the saddle having an outlet adjacent its upper opened side for directing the lubricant into a chamber on the lower end of the saddle and from which the oil is conducted to the depression of the bearing through a. duct or passage extending from the bottom of the chamber.

In the drawings- Figure l is a fragmentary side elevation of the improved saddle mounted on the top roll of a spinning machine.

Fig. 2 is a partial top plan view of the saddle.

Fig. 3 is a longitudinal section on line 3 3 of Fig. 2.

Fig. l is an end elevation of the saddle, and

Fig. 5 is a bottom plan view of the bearing end of the saddle.

The top roll l is preferably provided with a reduced shaft providing annular or peripheral grooves in which the kfront saddle 2 normally rests, said saddle being provided with a concave bearing 3 to receive the shaft of the roll. Centrally, the bearing is depressed, as at 4, and from this central depression leads a duct or passage 5, the same entering through the bottom of` a chamber 6 that is formed in the upper side of the saddle in such proximity to the lower end thereof as to have one side opening through the adjacent end wall of the saddle.

A lubricant or oil containing well 7 is also formed in the upper side of the saddle, the same being spaced inwardly from the chainber 6 although it communicates therewith through a duct S opening through the lower side wall of' said well. This duct is arranged close to the upper edge of the well, a

thin bridge of the metal being left to define the same.

The numeral 9 designates a wick which is inserted in the duct 8 so as to hang downV into the well for lifting the lubricant vtherefrom over the partitioning wall between the well and the chamber. This wicking is preferable although in actual practice it has been found that the heat from the bearing will cause suflicient capillary attraction to raise the oil up so as to flow through the duct 8 and drop or run down the side wall to the bottom of the chamber for further conduction through passage 5 .to the central depression 4- of the bearing.

It is obvious that in operation a lubricant, when placed in the well, will be drawn up by the wick for, discharge through opening 8 into chamber 6 and from thence to the bearing through passage 4. Consequently, constant attention to the greasing and lubrication of the bearings is unessential for a y quantity of the oil placed in the well will last a considerable length of time and provide a uniform lubrication of the bearing, doing away with extra labor and inconveniences as well as lessening the possibility of the bearing unduly heating. The operation of the roll will therefore be renderedmore efficient and the result more satisfactory.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent isl. A front top roll saddle having a bearing formed with a central depression, a lubricant well formed in the upper side of the saddle and having an outlet duct adjacent its lupper opened end, and a chamber also formedV in the saddle and provided with a well in its upper side provided with a duct leading from the upper portion thereof toward the lower end of the saddle. the latter being also formed with a chamber invits upper side adjacent its lower end into which the duct leads. a wick passing from the-'well through the duct and terminating` i'n the chamber, and meansV establishing unobstructed communication between the chamber and the bearing.

4. A top roll saddle having a bearing formed with a depression, a lubricant well,

-nieans connecting the well to the bearing,

and wick leading'f-rom the well and terminating short of the bearing depression to feed the lubricant Ytromvthe Well.

.5.. A top roll 'saddle having a bearing in its under side, a well having a lateral pas- Sage communicating with the bearing and a wick disposed in the lateral passage with one end extending down into the well and its opposite vend projecting a comparatively short distance beyond the outer end of the lateral passage and terminating short of the naine to thisspecication in the presence oi two' subscribing witnesses.
